I am using a GPIO pin to control an LED, active low.
It occurred to me that it might be possible to set the GPIO to high impedance (input and output disabled) when the LED is not in use.
However, it seems like only the first call to gpio_configurePin() has an effect. Is there any way to change the configuration of a pin after configuring it once?
Show LessHi,
In the 20732 SoC datasheet, it mentions that it fully supports Bluetooth Test Mode. I'm assuming then that it is also supported in the 20732S module. How is this mode activated in the module?
Is this mode "automatically" activated on power on if the HCI UART is connected?
Or is it related to the TMC pin (pull high)? Although, based on the post "Documentation on use of TMC pin?", the TMC pin is not available.
Thanks,
Mike
Show LessMy application has started resetting occasionally.
Is there any way to determine the cause of the reset when the application starts up?
I don't think it is caused by the watchdog, because I don't see any message on the trace output.
Show LessI noticed the functions bleapptimer_startAppTimer() and bleapptimer_refreshAppTimer() in bleapptimer.h
I thought maybe these could be used to set up a timer callback separate from the built-in ones, but they don't seem to work (or I am using them wrong).
Should something like this work, or do I need to build my own timer framework to multiplex the 'fine timer' callback?
Show LessWhat is the simplest way to keep the BlueTooth powered on at all times while I attempt to debug with it?
I can’t seem to find the exact API I need to use.
Show LessWe have two of the 20732 dev boards and they appear to have the same mac address: 20732A0C0FFE
This may be confusing things when we run them at the same time.
Is there a way to configure the MAC address on these boards?
Show LessI have built the HelloClient sample from the SDK but when I attempt to run it the LoadLibrary call fails and the assumed error in the sample code is "Broadcom Bluetooth profile pack for Windows (BTW) has to be installed". I am using an OEM part from IOGear that uses version 6.5.1.2700 of the BCM stack. Does anyone know of an additional installer that can the profile pack referred to in the error message?
Show LessI ran out of stack space in my application, but only discovered this by seeing clobbered ram.
1. is there any good way to detect stack overrun (e.g. declaring a variable at the top of the stack region and check for magic number? If so what is the best way to do this?
2. is there a way I can increase the allocation to the stack?
Thanks!
